 +====== Optimierung von Dansguardian ======

 +
 +Nachdem wir nun im ersten Schritt die [[centos:​dansg:​install|Erstinstallation und Grundkonfiguration]] von unserem Web-Content-Filter [[http://​dansguardian.org|Dansguardian]] erfolgreich abgeschlossen haben, machen wir uns nun in diesem Kapitel daran, die Installation unseren Bedürfnissen hin antzupassen und zu optimieren.
 +
 +===== Optimierung von Dansguardian =====
 +==== Anpassung Loglevel ====
 +Nach der erfolgten Inbetriebnahme drehen wir dem Dansguardian etwas die Luft ab, was heissen will, wir lassen uns nur noch die geblockten Seiten reporten, da das Logfile ggf. etwas arg überschwemmt wird mit Informationen,​ die uns eh' nicht interessieren.

 +</​code>​
 +==== Anpassung Authentication ====
 +Damit in den Logfiles die **User** angezeigt werden können, aktivieren wir noch die Option __**Auth plugins**__ in der Konfigurationsdatei //​**/​etc/​dansguardian/​dansguardian.conf**//​.
 +   # vim /​etc/​dansguardian/​dansguardian.conf
 +<​code>#​ Auth plugins
 +# These replace the usernameidmethod* options in previous versions. They
 +# handle the extraction of client usernames from various sources, such as
 +# Proxy-Authorisation headers and ident servers, enabling requests to be
 +# handled according to the settings of the user's filter group.
 +# Multiple plugins can be specified, and will be queried in order until one
 +# of them either finds a username or throws an error. For example, if Squid
 +# is configured with both NTLM and Basic auth enabled, and both the '​proxy-basic'​
 +# and '​proxy-ntlm'​ auth plugins are enabled here, then clients which do not support
 +# NTLM can fall back to Basic without sacrificing access rights.
 +#
 +# If you do not use multiple filter groups, you need not specify this option.
 +#
 +authplugin = '/​etc/​dansguardian/​authplugins/​proxy-basic.conf'</​code>​
 +An der aktiverten **proxy-basic.conf** ist weiter nichts zu ändern.
 +
 +<file bash /​etc/​dansguardian/​authplugins/​proxy-basic.conf>​
 +# Proxy-Basic auth plugin
 +# Identifies usernames in "​Proxy-Authorization:​ Basic" headers;
 +# relies upon the upstream proxy (squid) to perform the actual password check.
 +
 +plugname = '​proxy-basic'​
 +</​file>​
 +Ein anschließender Restart aktiviert unsere Änderungen.
 +   # service dansguardian restart
 +Somit werden nunmehr die Usernamen im Logfile mit ausgegeben und wir können später nach Bedarf, nach einzelnen Usern greppen.

 +Von Haus aus, ist der „ausgelieferte“ Dansguardian doch recht aggressiv eingestellt;​ d.h. viele doch erwünschten Seiten werden geblockt. Zum Erlauben dieser Seiten bearbeiten wir die Konfigurationsdatei //​**/​etc/​dansguardian/​lists/​exceptionsitelist**//​ für die Ausnahmeseiten.

 +#Don't bother with the www. or

 +#to just have '​foo.bar'​.
 +#
 +#You can also match IPs here too.

 +
 +#The '​grey'​ lists override the '​banned'​ lists.

 +#The difference is that the '​exception'​ lists completely switch

 +
 +#An example of grey list use is when in Blanket Block (whitelist)

 +
 +#Another example of grey list use is when you ban a site but want

 +==== separate Blacklists einbinden ====
 +Wem die grundlegenden Möglichkeiten von Dansguardian noch nicht ausreichen, dem sind separate **blacklists** ans Herz zu legen.
 +
 +Ein __**kostenpflichige**__ Sammlung von Blacklists((Listen mit unerwünschten Seiten)) kann bei Bedarf von [[http://​urlblacklist.com/?​sec=download|nachfolgender Adresse]]
 + ​heruntergeladen werden. Ob sich diese Investition lohnt, muss jeder für sich selbst entscheiden!
 +
 +Nachdem wir das Archiv **bigblacklist.tar.gz** heruntergeladen haben, entpacken wir den Inhalt kurzerhand nach //​**/​tmp/​**//​.
 +   # tar xzfv bigblacklist.tar.gz
 +
 +Anschließend kopieren wir das Verzeichnis mit samt seinem Inhalt in unsere Dansguardian-Konfigurationsverzeichnis //​**/​etc/​dansguardian/​lists/​**//​.
 +   # cp -fr /​tmp/​blacklists/​ /​etc/​dansguardian/​lists/​
 +
 +   cp: overwrite `/​etc/​dansguardian/​lists/​blacklists/​ads/​expressions'?​ y
 +   cp: overwrite `/​etc/​dansguardian/​lists/​blacklists/​ads/​urls'?​ y
 +   cp: overwrite `/​etc/​dansguardian/​lists/​blacklists/​ads/​domains'?​ y
 +
 +Eine detaillierte Beschreibung der einzelnen Listen ist in folgender Datei enthalten:
 +  * //​**/​etc/​dansguardian/​lists/​blacklists/​CATEGORIES**//​ enthalten.
 +
 +Eine Aufstellung von //positiven Seiten//, solche, die also keiner Sperre unterworfen werden sollen finden sich in den beiden Verzeichnissen:​
 +  * //​**/​etc/​dansguardian/​lists/​blacklists/​whitelist/​domains**//​
 +  * //​**/​etc/​dansguardian/​lists/​blacklists/​whitelist/​urls**//​
 +
 +Die Konfiguration bzw. das Einbinden der Domain-Listen aus den einzelnen Verzeichnissen erfolgt in der Konfigurationsdatei
 +//​**/​etc/​dansguardian/​lists/​bannedsitelist **//. Hier ist ebenfalls schon eine etwas kleinere Liste enthalten, welche aber aufgrund
 +des neuen und aktuelleren Umfangs ignoriert werden sollte, jedoch als Vorlage dienen kann, wie die einzelnen Domain-Listen
 +eingebunden werden können.
 +
 +In der Konfigurationsdatei //​**/​etc/​dansguardian/​lists/​bannedsitelist**//​ haben wir nun die Möglichkeit einzelne Einträge zu aktivieren, in dem wir das Zeichen **#** vor einer Zeile löschen, welche wir aktivieren möchten. ​
 +Im nachfolgendem Beispiel haben wir folgende beiden Zeilen aktiviert:
 +  * **.Include</​etc/​dansguardian/​lists/​blacklists/​sexuality/​domains>​**
 +  * **.Include</​etc/​dansguardian/​lists/​blacklists/​spyware/​domains>​**
 +
 +   # vim /​etc/​dansguardian/​lists/​bannedsitelist
 +<file bash /​etc/​dansguardian/​lists/​bannedsitelist>​
 +#domains in banned list
 +#Don't bother with the www. or the http://
 +
 +#The bannedurllist is for blocking PART of a site
 +#The bannedsitelist is for blocking ALL of a site
 +
 +#As of DansGuardian 2.7.3 you can now include
 +#.tld so for example you can match .gov for example
 +
 +#The '​grey'​ lists override the '​banned'​ lists.
 +#The '​exception'​ lists override the '​banned'​ lists also.
 +#The difference is that the '​exception'​ lists completely switch
 +#off *all* other filtering for the match. ​ '​grey'​ lists only
 +#stop the URL filtering and allow the normal filtering to work.
 +
 +#An example of grey list use is when in Blanket Block (whitelist)
 +#mode and you want to allow some sites but still filter as normal
 +#on their content
 +
 +#Another example of grey list use is when you ban a site but want
 +#to allow part of it.
 +
 +#To include additional files in this list use this example:
 +#​.Include</​etc/​dansguardian/​anotherbannedurllist>​
 +
 +#You can have multiple .Includes.
 +
 +# Time limiting syntax:
 +# #time: <start hour> <start minute> <end hour> <end minute> <​days>​
 +# Example:
 +##time: 9 0 17 0 01234
 +# Remove the first # from the line above to enable this list only from
 +# 9am to 5pm, Monday to Friday.

 +#and CONNECT tunnels except to addresses in the
 +#​exceptionsitelist and greysitelist files, remove
 +#the # from the next line to leave only a '​**s':​

 +Unter Umständen werdedn nun eine ganze Reihe von Seiten plötzlich nicht mehr erreichbar sein, weil diese eben auf eine der besagten **blacklists** steht (warum auch immer!).
 +
 +Hier hilft dann nur eine Detailsuche wo überall die Seite geblockt werden könnte. ​
 +   # grep webmail.trachtler.net /​etc/​dansguardian/​lists/​blacklists/​* -r
 +
 +   /​etc/​dansguardian/​lists/​blacklists/​mail/​domains:​webmail.trachtler.net
 +
 +Bei Bedarf muss also in der Datei //​**/​etc/​dansguardian/​lists/​blacklists/​mail/​domains**//​ einfach ein **#** vor der Zeile **webmail.trachtler.net** gemacht werden und die Seite ist wieder erreichbar.
 +

 +==== Optimierung der Dansguardian-Ressourcen ====
 +Die Standardeinstellungen,​ die Dansguardian aus dem RPM-Paket mitbringt, führen durchaus zu nicht unerheblichen RAM-Speicherverbrauch. Je nach Einsatz des Web-Contentscanners und der zu versorgenden Clients kann es zweckmäßig sein, die Systemparameter etwas anzupassen.
 +
 +In der zentralen Konfigurationsdatei //​**/​etc/​dansguardian/​dansguardian.conf**//​ passen wir die Werte beim Bereich **Fork pool options** die Parameter unserer Umgebung entsprechend an.
